It's not only about the USBX Device Audio class, but it's a general remark. When I import the existing project into CubeIDE workspace, I only get the minimum set of files. The most important source files are not available or they are replaced with templates when I (re)generate code, so it takes time and effort to copy the content from the examples, to fix compilation errors. Maybe I don't know how to do this right, but I tried different options with the same result again, and again. ST Team, could you please take a look into this?
@BKlus.1 What I found in examples for STM32H735G-DK was the incorrect setting for the memory byte pool. The result was 'not enough memory' error typically returned during the last thread creation. The next issue was the wrong PID assigned (0x5740) in device descriptor. The workaround was to assign correct PID, e.g. 0x5710 for CDC ACM and to use the ST tool to generate the .inf file if needed. This solved error code 10 and error code 28 in Windows.
Another issue in USBX examples is related to the descriptor generation for HS an FS mode, while we can only use FS mode. It's a complex and useless process in the example and this can also generate some UB, e.g. sometimes it stucks in endless loop due to descriptor size == 0. I was not able to reproduce this error, but it tends to occur during the same debugging sessions.
